17-year-old Marty McFly is accidentally sent back in time to 1955 in a time machine built from a DeLorean by eccentric scientist Emmett L. Brown, also known as "Doc". Upon arriving in 1955, Marty inadvertently causes his mother (Lorraine McFly) to fall in love with him, rather than with his father (George McFly). This begins to cause what Doc Brown later describes as a paradox that would cause Marty to disappear from existence. To make matters worse, Marty did not bring back any additional plutonium to power the time machine, so he must find the 1955 version of Doc Brown to help him reunite his parents and return to 1985. Biff Tannen, the antagonist, further complicates Marty's efforts to return to an unaltered 1985. Marty successfully causes his parents to fall in love and simultaneously ruins the future of Biff Tannen, who in the end is an auto detailer instead of George McFly's boss. Marty learns in the end that his family situation has improved because of the way his parents' relationship was changed by his intervention in the past. However, in the film's final moments, Doc Brown and the DeLorean appear and Doc tells Marty that he has returned from the future, and that Marty must come back to the future with him.
